by Systems analysis and design Activity Description: The aim of this activity to check students' understating about modeling the database using ER technique. Student will learn how draw the logical Entity Relationship diagram for the given case study using Online Visual Paradigm editor. The expected outcome is neatly create and labeled diagrams, which represents ER diagram. Activity: We want to build a system for a car garage. In a car garage the customer/client can buy a car, sell a car or get repaired a car. In the garage, there are two types of employees, one is salesman and other is mechanic. The salesman is responsible for selling and buying cars. The mechanic is responsible for repairing the cars. The cars are repaired through repair-job which is a weak entity associated to the entity car through weak association "repair”. Identify the possible entities and their attribute, the relationships among the attributes and draw the E-R diagram for the above mentioned activities and associations.

In each of Problems 1 through 4: Ga. Draw a direction field and sketch a few trajectories. b. Express the general solution of the given system of equations in terms of real-valued functions. c. Describe the behavior of the solutions as t → .. -1 3. X= х 5 -3)

Find the maximum value of ƒ(x, y) = 2x²y³ + 5 on the unit circle. (Give an exact answer. Use symbolic notation and fractions where needed. Enter DNE if there is no maximum.) maximum: Find the maximum value of ƒ(x, y) = 2x²y³ + 5 on the unit circle. (Give an exact answer. Use symbolic notation and fractions where needed.

The store manager of a local supermarket is interesting in determining the relationship between the quantity of milk purchased by customers, measured in litres, and quantity of breakfast cereal, measured in kilograms. Using monthly data across all months in 2019 and 2020, the following model was estimated: Y = 9.71 + 0.53 X Error sum of squares: 328.2 Sum of The store manager of a local supermarket is interesting in determining the relationship between the quantity of milk purchased by customers, measured in litres, and quantity of breakfast cereal, measured in kilograms.

30 ft OS Problem 2. Wind blows on the side of a building as shown. If the structure is used as a business and is located in an open terrain with scattered obstructions less than 30 ft high, determine the minimum design wind pressure on the windward wall, the leeward wall and the roof. Assume the ground is flat and the structure is located in Arizona. Use Cp 30 ft OS Problem 2. Wind blows on the side of a building as shown. If the structure is used as a business and is located in an open terrain with scattered obstructions less than 30 ft high, determine the minimum design wind pressure on the windward wall, the leeward wall and the roof. Assume the ground is flat and the structure is located in Arizona. Use Cp = -0.7 for both windward and leeward sides of the roof. 100 ft with minimal
